Commentary

### SUMMARY
Proverbs 15:7 illuminates the profound contrast between the wise and the foolish, particularly concerning their communication and its underlying source. It asserts that the lips of the wise actively and generously share knowledge, disseminating truth and understanding for the benefit of others. Conversely, the heart of the foolish fails to do so, indicating an internal deficiency—either a lack of genuine knowledge to impart or an unwillingness to share it—thereby highlighting that one's words are a direct reflection of their inner character and wisdom.

### CONTEXT
* **Literary Context:** Proverbs 15:7 is situated within a larger collection of Solomon's proverbs (beginning in [Proverbs 10:1](/proverbs/10-1 "Proverbs 10:1 - Solomon's Proverbs")), which frequently employs antithetical parallelism to highlight the stark differences between wisdom and folly, righteousness and wickedness, and their respective outcomes. This verse specifically contrasts the verbal output and internal state of the wise with that of the foolish, fitting seamlessly into the book's overarching theme of practical wisdom for daily living. It follows verses that discuss the nature of a soft answer versus grievous words ([Proverbs 15:1](/proverbs/15-1 "Proverbs 15:1 - A Soft Answer")), the tongue of the wise ([Proverbs 15:2](/proverbs/15-2 "Proverbs 15:2 - The Tongue of the Wise")), and the eyes of the Lord ([Proverbs 15:3](/proverbs/15-3 "Proverbs 15:3 - The Lord's Omniscience")), all of which underscore the power and accountability of speech and inner disposition.
* **Historical & Cultural Context:** In ancient Israel, wisdom was highly valued and often associated with divine revelation and practical discernment for navigating life's complexities. The "wise" (חָכָם, _châkâm_) were respected figures, often elders or scribes, who possessed insight into God's ways and could offer sound counsel. Education was primarily oral, making the spoken word a primary vehicle for transmitting knowledge, tradition, and moral instruction. The concept of the "heart" (לֵב, _lêb_) in Hebrew thought was far more comprehensive than merely the seat of emotions; it encompassed the totality of a person's inner being—intellect, will, conscience, and moral character. Thus, a proverb about the "lips" and the "heart" would have immediately resonated as a statement about the integral connection between one's inner disposition and outward expression, particularly in a society where public discourse and communal teaching were central.
* **Key Themes:** This proverb contributes to several key themes prevalent throughout the book of Proverbs. Firstly, it emphasizes the **power and responsibility of speech**, illustrating that words are not neutral but carry significant impact, either for good or ill. The wise use their words to impart knowledge, while the foolish fail to do so, often speaking destructively or idly (cf. [Proverbs 10:31](/proverbs/10-31 "Proverbs 10:31 - The Mouth of the Righteous")). Secondly, it underscores the **heart as the source of all action and expression**. The quality of one's speech is directly linked to the condition of their heart, reinforcing the idea that true wisdom is an internal state that manifests externally (cf. [Proverbs 4:23](/proverbs/4-23 "Proverbs 4:23 - Keep Your Heart")). Finally, it highlights the **contrast between wisdom and folly**, a foundational theme in Proverbs, by presenting a clear dichotomy in character and conduct, urging the reader to choose the path of wisdom and its beneficial outcomes.

### EXPOSITION AND ANALYSIS

#### Key Word Analysis
* **disperse (Hebrew, _zârâh'_):** From H2219, meaning "to toss about; by implication, to diffuse, winnow; cast away, compass, fan, scatter (away), spread, strew." This word paints a vivid picture of active, widespread distribution, much like a farmer scattering seeds or winnowing grain. It implies intentional and generous sharing, not merely speaking, but broadcasting knowledge so that it can take root and yield fruit in the lives of others. It suggests an abundance of knowledge that cannot be contained but must be spread abroad.
* **knowledge (Hebrew, _daʻath'_):** From H1847, meaning "knowledge; cunning, (ig-) norantly, know(-ledge), (un-) awares (wittingly)." In the context of Proverbs, this refers not merely to intellectual information but to practical, moral, and spiritual insight—understanding how to live skillfully and righteously in accordance with God's ways. It is wisdom applied, truth understood and ready to be imparted.
* **heart (Hebrew, _lêb'_):** From H3820, meaning "the heart; also used (figuratively) very widely for the feelings, the will and even the intellect; likewise for the centre of anything." In biblical anthropology, the heart is the core of one's being—the seat of intellect, will, emotions, and moral character. It is the spring from which all actions and words flow. Therefore, the "heart of the foolish" signifies a fundamental internal deficiency, a lack of wisdom, discernment, or moral integrity that prevents them from acquiring or sharing beneficial knowledge.

#### Verse Breakdown
* **"The lips of the wise disperse knowledge":** This clause presents the positive characteristic of the wise. Their "lips" (metonymy for their speech or communication) are not passive but actively "disperse" or scatter "knowledge." This implies a deliberate, generous, and fruitful sharing of insight, understanding, and truth. The wise are not hoarders of information but conduits through whom valuable wisdom flows out to enrich others.
* **"but the heart of the foolish [doeth] not so":** This clause introduces the stark contrast. The "heart" of the foolish—representing their inner core, their intellect, will, and character—is the source of their inability or unwillingness to disperse knowledge. Their internal deficiency means they either lack true knowledge to share, or they possess it but are unwilling to impart it, perhaps due to selfishness, pride, or a lack of discernment regarding its value. Their outward expression (or lack thereof) directly reflects their inner emptiness or corruption.

#### Literary Devices
Proverbs 15:7 masterfully employs **Antithetical Parallelism**, a hallmark of Hebrew wisdom literature, by juxtaposing the actions and characteristics of the "wise" with those of the "foolish." This creates a clear and memorable contrast, highlighting the distinct outcomes and behaviors associated with each. The proverb also uses **Metonymy**, where "lips" stand for the speech that issues from them, and "heart" represents the entire inner person—their intellect, will, and moral character. This emphasizes that outward expressions are a direct reflection of inner disposition. Furthermore, the verb "disperse" (זָרָה, _zârâh'_) evokes **Imagery** of scattering seeds, suggesting a generous, widespread, and potentially fruitful dissemination of knowledge, contrasting sharply with the barrenness implied in the foolish person's inability to do likewise.

### THEOLOGICAL AND THEMATIC CONNECTIONS
This proverb deeply connects to the biblical understanding of wisdom as a divine gift and a moral imperative. True wisdom, rooted in the fear of the Lord, is not merely intellectual accumulation but a dynamic, life-transforming force that compels its possessor to share its benefits. The act of "dispersing knowledge" aligns with God's own nature as a giver of wisdom and truth, reflecting a stewardship of divine insight. It underscores the theological principle that what is within a person's heart will inevitably manifest in their words and actions, confirming that the mouth speaks from the abundance of the heart. This proverb calls believers to cultivate hearts filled with God's wisdom, enabling them to be channels of truth and understanding in a world often starved for genuine insight.

* [Proverbs 10:31](/proverbs/10-31 "Proverbs 10:31 - The Mouth of the Righteous")
* [Proverbs 16:23](/proverbs/16-23 "Proverbs 16:23 - The Wise Heart Teaches the Mouth")
* [Matthew 12:34](/matthew/12-34 "Matthew 12:34 - Out of the Abundance of the Heart")

### REFLECTION AND APPLICATION
Proverbs 15:7 serves as a profound mirror, inviting us to examine the quality and source of our own words. Do our "lips" genuinely "disperse knowledge"—whether it be spiritual truth, practical wisdom, encouragement, or sound counsel—in our daily interactions? Or do our words betray a "heart" that is lacking, perhaps filled with trivialities, negativity, or an unwillingness to share what is good and edifying? This verse challenges us to move beyond mere intellectual assent to wisdom and to actively embody it, allowing it to flow generously through our communication. It calls us to cultivate a heart that is continually nourished by God's Word and Spirit, so that our speech may consistently build up, enlighten, and guide others. True wisdom is not hoarded; it is shared, becoming a blessing to both the speaker and the hearer, reflecting the very nature of God, who generously imparts His truth.

#### Questions for Reflection
* **What kind of "knowledge" am I currently dispersing with my words? Is it beneficial, edifying, and truthful?**
* **How does the condition of my "heart" manifest in the way I speak and interact with others?**
* **In what specific ways can I be more intentional about "dispersing knowledge" in my family, workplace, or community?**
* **What steps can I take to cultivate a "heart" that is richer in wisdom and understanding, so that my words may be more impactful?**

### FAQ

**What does "disperse knowledge" mean in a practical sense today?**

Answer: In a practical sense, "disperse knowledge" means actively and generously sharing valuable insights, understanding, and truth with others. This isn't just about lecturing or showing off; it's about discerning what is helpful and then communicating it effectively. It could involve offering wise counsel to a friend, teaching a skill to a colleague, sharing spiritual truths from [God's Word](/psalms/119-105 "Psalm 119:105 - Your Word is a Lamp") with a fellow believer, or simply speaking words of encouragement and clarity that bring understanding to a confusing situation. It implies an outward flow of wisdom that benefits the listener, much like a spring freely gives water.

**Why is the "heart" emphasized as the source of speech in this proverb?**

Answer: The emphasis on the "heart" in this proverb, as well as throughout biblical literature (e.g., [Proverbs 4:23](/proverbs/4-23 "Proverbs 4:23 - Keep Your Heart")), highlights the foundational biblical truth that one's words are a direct outflow of their inner character and disposition. The "heart" in Hebrew thought is not just emotions, but the core of one's intellect, will, and moral being. Therefore, if the "heart of the foolish" does not disperse knowledge, it's because their inner self lacks true wisdom, discernment, or the generous spirit to share it. Conversely, the wise person's ability to disperse knowledge stems from a heart cultivated with understanding and truth, as Jesus Himself taught in [Matthew 12:34](/matthew/12-34 "Matthew 12:34 - Out of the Abundance of the Heart").

### CHRIST-CENTERED FULFILLMENT
Proverbs 15:7 finds its ultimate fulfillment in Jesus Christ, who is the very embodiment of divine wisdom and the supreme dispenser of knowledge. Unlike the foolish, whose hearts are barren, Jesus's heart was perfectly aligned with the Father, overflowing with truth and grace. His "lips" constantly "dispersed knowledge" in a way that transformed lives, from His Sermon on the Mount ([Matthew 5](/matthew/5 "Matthew 5 - The Sermon on the Mount")) to His parables and direct teachings. He spoke with unparalleled authority and insight, revealing the deep things of God and the path to eternal life ([John 6:68](/john/6-68 "John 6:68 - Words of Eternal Life")). He is the "Lamb of God" ([John 1:29](/john/1-29 "John 1:29 - Jesus, the Lamb of God")) who fully revealed the Father's character and will. Furthermore, through His Spirit, Christ transforms the "heart of the foolish" into a heart capable of receiving and dispersing divine knowledge ([Ezekiel 36:26-27](/ezekiel/36-26 "Ezekiel 36:26 - A New Heart and Spirit")). As believers, we are called to have the mind of Christ ([1 Corinthians 2:16](/1_corinthians/2-16 "1 Corinthians 2:16 - The Mind of Christ")), allowing His wisdom to dwell richly within us, so that our lips, empowered by the Holy Spirit, may also "disperse knowledge" for the glory of God and the edification of His church ([Colossians 3:16](/colossians/3-16 "Colossians 3:16 - Let the Word of Christ Dwell Richly")).
